Averages over 30 years, not a forecast.
- Normals: the Canadian Climate Normals, 1991–2020, at L'Assomption (the closest location with all twelve months of temperatures).
- Other locations: a location missing months of precipitation or snow is filled from the nearest that has them all, never mixed month by month.
- Comparisons: the 2,500-plus towns and neighbourhoods of Canada, each read from its closest normals location; whole cities and reserves aren’t counted.
- Not on this page: sunshine, absent from every 1991–2020 location, and an altitude correction, for want of the town’s own elevation.
